The TVR20 Series BACNet Controllers have been designed for pressure independent and pressure dependent VAV control.  The controllers can measure the flow across the VAV box and control it's position to the required flow setpoint. The flow (setpoint) is adjusted by the temperature control loop providing accurate temperature control.
 
The TVR20 Series BACNet VAV controllers can have additional VOC (Volatile Organic Compounds), Relative Humidity or PIR Occupancy sensors. Additional VOC, dehumidity/humidity control loops expand the multi-functional controller further. The fresh air quantity provided by the VAV Box can be automatically increased as required.
 
With the TS-Option the room controllers are supplied with an attractive colour touchscreen display with glass front that provides intuitive user interface. The display colour scheme can be tailored using different skin colours. The controllers are mounted on the wall surface directly or to standard wall mounting boxes. The controllers have built-in BACNet MS/TP communication that allow interaction to the BMS systems (Building Management Systems). Optional Bluetooth wireless interface provides connection to Smart Phone App interface (iOS).
 
The TVR20 BACNet VAV controllers can be configured using Windows Device Configuration Tool (connected wirelessly using Bluetooth) or from SmartConfig iOS app. The TVR20 controllers are available in white and black (in addition to the touchscreen colour skins). For ease of commissioning the controller address can be set from the bit switch or from the touchscreen.
